Blue Bridge Cup ALGO-93 inverse number (math, function)

"Ideas": Use of Atoi and itoa, note atoi, three parameters. The first one is the number to convert, the second is the one that is stored in that string, and the third is what the binary is.

"AC Code":

#include <iostream> #include <algorithm> #include <string> #include <cstdio> #include < cstring>using namespace std; #define MAX 20+2int reverse_num (int x) {int i = 0;char A[max];itoa (x, A, ten); for (i = 0; I & Lt Strlen (a)/2; i++) {Char temp = a[i];a[i] = A[strlen (a) -1-i];a[strlen (a) -1-i] = temp;} Return Atoi (a);} int main () {//freopen ("In.txt", "R", stdin); int i = 0, sum = 0;int A = 0, b = 0;; Cin >> a >> b;int m = Reverse_num (a), int n = reverse_num (b); sum = m + n;cout << reverse_num (sum);}
